On a less cynical note:
I would be interested in seeing some waveforms, both the transmiting end and the receiving end with both standard cables and hand made ones, and a few eye diagrams should show us what is going on.

When I post this SATA cable on Taiwan's audio forum a month ago
Every one's reaction as you like
However, there are always someone willing to try new things
After the test every were found
Different kind of SATA cables made considerable change of the sound
So I am very happy to tell you this message
And I am glad mail my sata cable to qusp for test
If qusp would post a test report
At the same time
I will mail my sata cable to Yatin Narsai in South Africa for test
Perhaps after a few days we could see Yatin Narsai's results

I am a senior electrical engineer over 30years
Need no handicraft to make living
Do these things mainly because of hobby

So as a senior engineer with 30 years experience you will have some plots of the wave forms with different cables and possibly eye diagrams to show what is happening to the digital signal. As you are aware digital signal transmission and transmission line theory have been around for quite a while (Heaviside), and in the case of SATA data transmission if there is the sound difference you claim then we need to know what is causing it and that requires examination of the digital signal, which can only be done by looking at the transmitted waveforms.
Now if I seem cynical its because I am, there are lots of magical claims (myths) filtering into the digital world regarding digital in relationship to audio, and I am sorry but from my own experience with digital I know you have to look at the signal transmission and the waveform shapes to determine what is happening and from these results determine what is going on.

Than you can tell us how it works. Normal SATA dosnt loose bits or give errors (or your Word documents would get corrupted) and the SATA timing has nothing to do with the final audio (the DAC does that). The only possible explanation ( and I dont buy it ) is noise pickup, and an easy test to prove that is to compare two normal SATA cables, one a lot longer than the other.

Because the performance of the SATA cable to the sound improvement was significant
Can be said the the SATA cable is the most critical components to PC audio
So even if you must spend a lot of time to make a SATA cable
But you will get amazing rewards

Server to Computer digital SATA transmission that gets "coloration".... interesting at least. Have you noticed any change when looking at pictures from the hard drive, like more detailed definition or maybe some reddish or blueish distortion? In theory, because of the silver wires, they sould appear brighter at least.
Maybe, even video files acquire better resolution, like an SD movie apearing as to be an HD film...

I would like to try this at work, to see if my Word files get any improvement ('cause writing documents is not my best), maybe on-the-fly grammar correction.... who knows?

Just as identical files at different hard-drive locations, wav and identical wav decoded from flac (stored on the drive first or decoded to ram first), and many other issues. Because "everything matters". But what you will almost never find are reports about simple yet credible ABX tests to support the claims.

Its digital, its digital signal transmission, storage, etc, there is no magic about it, its good engineering and physics, and when it comes to digital signals etc you cannot apply the same sort of psuedo mystical factors to it. What you dont find is hard empirical data, eye diagrams and a reasonable explanation of why digital signals related to audio have mystic powers compared to the day to day mundane digital, where these effects are not present and are not discussed! Its not often you see tweeker ideas for say a MRI scan or even controlling the magnetics for a particle accelerator...
Maybe these audio related digital bits dont realise that they are digital (0 or 1) and think they are half analogue/half digital... Of course after all these digital signals have passed through the various buffers from the hard drive to the DAC and thus on the way be re-created any artefacts from downstreem will have been obliterated.........
